Referring to the drawings indetail a dupli- I eating machine s of known construction isl'in-f dicated at 1 and which includes, as is well known, an 'adhesive'duplicating film, web or apron 2, hereinaftertermed a film and which winds'oif 'andon the rollers 3, 4. Adjacent the outer face of one side, of the frame of the machine atrack member 5 is arranged and further includes a platform 7 ,for'supportingf the film 2 between the rollers 3, 4:. v The platform 7 has depending ends of arcuatecross 1 section over Whichthe'ffilmfZ passes. The foregoing elements are illustrated for the purpose of clearly showing the adaptation of I a-device, in accordancejwiththis invention,

with respect toa duplicating or reproducing I machine.

Figure 5 is'a fragmentary view in e'leva-fi I, ftlon of the pressing roller and its support;v f1

supported in spaced'bracket's 6. r The machine s In dup licating machines; they include a i pressing roller the function of which is' to press a sheet of paper upon the filmi2 for the v 95 purpose of taking-up an impression by the V sheet from the film 2. The-"pressing roller when functioningis shifted from the rear to the forward encl'of the machine. ,The pres's- "ing roller is'carried byja suitablesupporti at 10 is formed with an apertured extension;

' wall 15 has connected thereto an upstanding which is slidably mounted on the track memher 5. The form of support for the pressing roller as disclosed is different from the form now employed. The support as illustrated is indicated at 8 and is of yoke-shaped contour. Pivotally mounted in the arms of the support is the pressing roller 9 which is of a diameter to project from the inner edge of the support 8. See Figure 4. One of the arms of the support, such arm being indicated 11 for the purpose of slidably mounting the support on the track member 5. The exten sionll is formed with a lug or protuberance 12 which constitutes a stop when the support 8 is thrown to its outward position or rather when the pressing roller 9 is moved to inactive position and which is in a direction away from the machine. When the roller 9 is in active position it extends transversely'with respect to the'film 2. The support 8 also constitutes a hand grip when moving the pressing roller 9 from the rear end to the forward end of the machine for the purpose of providing an impression on the sheet of paper which the roller 9 travels over.

The device includes a carrier in the form of a rectangular tray of the desired length,

'width and height and referred to'generally at 13. The tray consists of a bottom 14, rear end wall 15 and a pair of side wails 16. The bottom 14C in proximity to the rear end wall 15 is provided with a transversely ex-. tending, rectangular slot 17 coextensive with the width of thebottom 1 1. The side walls 16 at the ends of the slot 17 are curved in an arch-like manner as indicated at 18. The slot 17 provides in connection with the curved edges of the sides of the tray at the ends of the slot a concaved throat for the successive discharge of thesheets of the pack of sheets 19 which are arranged or supported by the tray 13. The manner in which the throat is formed permits a portion of the adhesive tape to project slightly above the bottom of the tray and make contact with the bottom sheet of paper of the pack when the tray is in its lowermost position, therefore eliminating av depressor arrangement for the sheets. The

end portion 14 of the bottom forms a sup-' port for one end of a pack of sheets.

The sheets of the pac'klQ correspond to the interior length and width'ofthe tray 13..

The sheets ofthe pack 19 are indicated at 20.

Each of the side walls 16, at a point directly in advance of the slot-17 is formed with an inwardly extending lug 21 to prevent the pack from shifting over thetop edges of the tray. Each sidewall 16 in proximity to. the forward end is formed with a vertically disposed lug 22 formed with an aperture 23. The end handle piece or member 24.

The forward end of the tray v13 is supported above and pivotally connected with sides of the tray at the bottom of said sides.

Secured to each side of the frame of the machine below the top edge of the side is a bearing device or member for pivotally supporting the lower ends of the portions 26 where by the tray is pivotally connected with the machine frame. With reference to Figure 6 the construction of each bearing member is shown and it consists of a disc 27 positioned against the upper face of the'side of the machine frame. Centrally of the outer face of the disc 27 is a shank 28 which is mounted inan opening 29 formed in the side 30 of the machine frame. The shank 28 projects inwardly from said side 30 and is threaded. Engaging with the'threaded portion of the shank isa securingnut 31 for maintaining the bearing member in position.

The outer face of the disc 27 centrally thereof has extending therefrom a pivot 32 for the lower end of a portion 26 of the yokeshap'ed member and the pivot 32, which ,constitutes a bearing extends through an opening 33 formed in the portion 26 of the yoke-' shaped member; The portions 26 of the yokeshaped member are the arms thereof. The discs 27 space the arms 36 from the sides 30 of the machineframe. j

'The tray 13 has pivotally'connected tothe sides thereof forwardly of the slot 17 a pair of supporting arms 34: each providedwith an inwardly. extending lug 35.. The arms 34; are provided for maintaining the rear of the tray in an elevated position when the device. is not employed for feeding and aligning purposes. The normal position of the arms 34 are as illustrated in Figure 2 and with the lugs 35 engaging the tray to arrest the rip-h ward shifting movement of the arms relative to the tray. fvVhen'the arms 34 are employed to maintain the rear of the tray in an elevated position, said arms are swung to a vertical position and rest on the frameof the machine. Pivotallyconnected with the tray is a tensioned follower element which normally seats 4.
